NUT-LOCK.

To all whom it may concern Be it known that I, TIMOTHY E. TAYLOR,

' a citizen of the United States, residing at- Thompson, in the countyof \Vindham and State of Connecticut, have invented certain new anduseful Improvements in Nut- Locks, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to nut locks and the principal object of the sameis to provide a nut lock in which a plate is provided with a flange inwhich a locking key is slidably mounted. It should be noted that thelocking key is so constructed that it not only locks the nuts againstrotation, but also prevents its own withdrawal.

This invention is illustrated in the accompanying drawings, whereinFigure l is a perspective view of the end portions of a pair of railsections, and shows the improved nut lock connected therewith. Fig. 2 isa View in elevation with a slightly modified type of nut lock from thatshown in Fig. 1. Fig. 3 is a View in cross section along the line 3-3 inFig. 2. Fig. 4 is a perspective view of the locking tongue used in Fig.2.

In the accompanying drawings, the numerals 1 and 2 indicate railsections which are connected together, and which are provided with theusual fish plates 3. Bolts 4: are passed through the rail sections andfish plates and a plate 5 is placed upon the ends of the bolts and fitsagainst the fish plates. The plate 5 is provided at its upper end with aflange 6 which forms a track for the reception of a locking key 7. Thekey is provided with a flange 8 which extends along the sides of thenuts 9 which are threaded upon the ends of the bolts 4 after the plate 5is in position. In Fig. l, I have shown the flange 8 with its centralportion cut away from the key to form a Specification of Letters Patent.

pair of tongues 10 which are bent along the sides of the inner nuts 9.The outer ends 11 of the key 7 are bent over the ends of the fish plate3 and also assist in preventin movement of the key.

In Figs. 2 and 4 I have shown a slightly modified form of locking key inwhich the flange 8 is cut to each side of the center at a point flushwith the inner ed es of the inner nuts 9, and from the key i to form thetongues 10 which are bent down to contact with the sides of the nuts 9and prevent the key from slipping out of place.

After the plate 5 has been placed upon the bolts 4, the nuts 9 arethreaded in place and turned so that their upper edges will be parallelwith the flange 6. The key is passed through the track formed by theflange 6 with its flange 8 contacting with the sides of the nuts 9, toprevent their rotation. The tongues 10 are bent to contact with thesides of the inner nuts 9 and the end portions 11 of the key are bentover the ends of the fish plates to form an additional lock for the key.

that I claim as my invention is A nut lock comprising a plate having oneside bent to form an overhanging flange, a strip resting upon said plateand beneath said flange, and an outwardly extending flange formed uponsaid strip and provided with slits formed adjacent the center andleading toward the center to form tongues extending from the centralportion of said flange in opposite directions and adapted to be bent toengage the side faces of a pair of nuts to hold the stri in place.

In testimony whereof hereunto aflix my signature in presence of twowitnesses.
